- 10 resistance.

The principal object of my invention is to provide an improved type of governor construction capable of more accurate governing action than any devices of the prior art.

15 A further object of my invention is to provide an improved governor of the type described that is extremely simple in construction, one which is easily and simply installed and will not easily become broken or out of order. A further object 1 of my invention is to provide an improved adjusting means for governors of the type described.

A further object is to provide improved adjusting means whereby the entire governor assembly may be adjusted about the governor valve. A further object of my invention is to provide an improved construction whereby the plate upon which the governor mechanism is assembled may be adjusted within the governor.

Other objects and advantages will be more 30 apparent from the following description wherein reference is had to the accompanying two sheets of drawings upon which:

Fig. l is a side view of my improved governor with the cover plate removed;

Fig. 2 is a similar view thereof, showing the plate and all parts assembled thereon in a changed position; Fig. 3 is a vertical sectional view of the governor taken generally on the lines 3-3 of Fig. 1; 40 and Fig. 4 is a similar section through the conduit and valve portion taken generally on the lines 4-4 of Fig. 3.

My improved governor may be constructed of 45 a pair of aluminum die castings l and I2 which are suitably bolted together to form a governor body and a housing respectively. The body ill may be provided with suitable bolt openings l4 and 16 so that the same can be fastened in the 50 intake manifold of an automotive engine. The body It is also formed with a square passageway 18 adapted to be aligned with the passageway in the intake manifold conduit. An offset valve plate 20 is adapted to be positioned in the pas- 55 sageway l6 and is mounted upon a suitable shaft 1935, Serial No. 27,577

22 which is Journalled in suitable ball bearing members 24 and 26 positioned in the openings 26 and 30 in the governor body II). It will be noted that the shaft has a flattened portion 30 upon which the valve plate is fastened, to which the plate is secured by suitable screw members 32. The shaft is adapted to be held against lateral movement by a suitable locking ring 24 fastened over a reduced shoulder 35 adjacent the ball bearing member 26. A gasket ring 36 positioned in the opening 36 prevents air from being drawn through the housing l2 to the passageway l8 as will be more clearly explained hereinafter. The ball bearing member 24 is adapted to be held in position by a spring washer member 36 and the end of opening 26 is adapted to be closed by a similar spring washer member 40.

The shaft 22 may extend through an opening 42 in the governor housing I2 through a suitable bushing member. 44 which is an enlarged portion positioned in the opening 30. The shaft 22 may extend through a plate member 46 and have an arm 48 secured to its outer end. The arm 48 may have a pin 50 in the end thereof upon which a roller member 52 is mounted. The roller member 52 is adapted to engage the end of a multiple leaf spring 54 that has its one end fastened in a clamp or support member 56. The support member 56 has a stud portion 51 extending into a suitable opening 58 in the plate 46, within which the same is rotatably mounted. The support 56 is formed upon one side with a segmental gear portion 59 that is adapted to mesh with a worm 60. The worm 60 may have a reduced portion 6| journalled in a boss 62 formed in the plate 48 and its other end 63 journalled in a. similar boss 64 formed in the plate 46. The end 63 may be formed with a screw driver slot 65-50 that the worm may be rotated in this manner. The worm is also provided with an enlarged portion 61 within which a pair of cross bores 68 are provided for the purpose of permitting rotation of the worm by inserting a pin in the bores and rotating the same.

As thus far described the governor may be similar to that shown in my recently issued Patent Number 1,999,758. However, in order to provide a wider range of operation and a more effective means of adjustment for the governor setting, I have mounted the spring 54 and spring support 56 upon the plate member 46.

The plate member 46 is adapted to be mounted against the inside wall of the governor housing l2. The plate may have an opening ll through which the bushing 44 of shaft 22 extends 48 against wall ll of the housing.

The plate 44 may be formed with limit stops l4 and II for the purpose of defining the travel of the arm or lever 48. The plate may be further forlned with a' segmental gear portion 18 adjacent one end thereof adapted to engage a worm II. The worm I0 is formed with a reduced end portion fl'journalled in a suitable pass in the housing I! and provided at its opposite end with an enlarged head portion 84 formed with the end slot 88. The slot '6 is adapted to be engaged by the end of a lock tumbler B8 suitably mounted in the housing and providing means for adjusting the position of plate 46 from the exterior of housing II. The cover 90 for the housing I! is adapted to be locked into position in the annular groove 92 of housing I! and is provided for this purpose with a downwardly depending lug 94 formed with an opening 98 through which the barrel of lock 08 is adapted to pass. This construction is Similar to that shown in my issued Patent Number 1,966,722.

with the construction which I have shown and described it will be obvious that in order to secure a setting of the governor to operate to close off the supply of fuel at a predetermined speed, this can be accomplished by rotating the plate 46 clock-wise or counter clock-wise as desired 'to increase or decrease the governing speed. In view of the fact that by changing the position of the support 56, the tension of the spring member 54 is shown and it can be seen that it is highly desirable to always keep the same proportionate tension upon the spring 54 and the only method by which this can be accomplished is by rotating the entire assembly or plate 46. With this construction, it will be obvious that if a governor is operating accurately at a given speed that the setting may be changed by rotating the plate 46 and the same accurate functioning hereby secured to any other speed.

While I have illustrated and described a speciflc embodiment of my invention incorporating a multiple leaf spring, it will be obvious that various different types of springs or other resistance means may be employed without departing from the spirit of' this invention and I contemplate that changes and modifications may be made in the actual details shown and I do not desire to be limited in any particular; rather, what I desire to secure and protect by Letters Patent of the United States is:
